Sirach 43:26 (KJV) “By him the end of them hath prosperous success, and by his word all things consist.”

Colossians 1:17 (KJV) “And he is before all things, and by him all things consist.”

The suggestion comes from  Sirach 43:26 as the background of Colossians 1:17.

The author there attributes the quoted translation of Sirach to Brenton’s LXX, which is true but not the full truth. Brenton’s LXX used the KJV for the English translation of the Apocrypha (except for 3rd and 4th Macabees which Brenton translated himself, or he at least found a translation of those other than the KJV, since the KJV did not include those two books of the “Apocrypha”).
